BENGAMIN G. SHALET, OF BRIDGEPORT, CONNECTICUT.

BELL.

Application filed April 29, 1915.

To all whom it may concern:

Be it known that I, BENGAMIN G. SI-IALET, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented cer ain new and useful Improvements in Bells, of which the following is a specification.

This invention relates to new and useful improvements in alarm bells or gongs such as are used on electric street railway cars and like vehicles for the purpose of giving an alarm to persons ahead, and can obviously be used for other purposes and in other places where a bell of its type would. be required.

The purpose of the invention is to generally improve upon that class of bell shown and describedin my prior patent of March 25, 1913, #1,057,012 and particularly to produce a bell which will be simple in construction, inexpensive to manufacture and wherein the use of springs will be eliminated; and further to construct and arrange the parts so that they will always assume an operative position after the bell has been sounded; further to provide a bell whichcontains a pair of striking hammers that operate alternately upon the bell and in quick succession.

With these and other objects in View the invention resides and consists in the con struction and novel combination and arminor details of construction within the,

scope of the claims may be resorted to without departure fro-1n the spirit or sacrificing any of the advantages of the invention.

Similar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification, and upon which,

Figure 1 shows a sectional elevation of the bell including the casing inclosing the operative parts of the same, and F ig. 2 shows an inverted plan view of the device shown in Fig. 1, the casing being broken away.

Referring in detail to the characters of reference marked upon the drawings 5 represents the casing of the bell, which is adapted to be bolted or otherwise secured to the underside of a car platform so that the pedal Specification of Letters Patent.

or operating member will project above the floor of the platform in position to be engaged by the foot of the operator. In practree thls casing is preferably formed of cast metal and serves to inclose the major portion of the bell mechanism and further includes an external lug 6 to which the bell 7 is hung. An operating lever 8 is pivotally hung upon a stud 9 secured in-the casing. This lever is of an irregular shapeand somewhat resembles a bell crank lever, except that its pivotal point is not located in the elbow, but near the operative end. This operative end 10 extends up at a right angleto the upper portion of the lever and is provided with a head against which the foot of the operator engages. The pivot for the lever is located relatively near its outer end portion and the greater portion of the lever hangs within the casing below the pivotal stud 9 and thus serves as a weight 11 to throw the outer and operative ends 10 up in position tobe engaged at all times. This outer end projects higher when engaged than when released. The movement of the lever is limited in one direction by the stop 33 and in its upward direction by a second stop 34. A second lever 12 is hung upon a central stud 13 secured to the casing and includes a downwardly extended portion that is connected to the lower end 11 of the before mentioned lever 8 by links 15. Segments l6 and 17 are formed on the short end of the lever 12. The high points 18 and 19 on the two segments are arranged alternately with respect to each other so that but one. can be in position to raise a trip lever at one time. The two trip leversQO and 21 are arranged side by side and substantially parallel to each other. -They are pivotally mounted upon a stud 22 secured to the easing and are each provided with a lug 23 upon their under side to be operated by the segments 16 and 17 before mentioned. The weighted ends 24: of these levers serve to hold the said lugs down in engagement with the segments at all times, while the free ends 25 of the said levers serve to engage the short ends 26 of the striking hammers 27 and 28 which are pivoted upon a stud 29 that is also secured to the casing. The outer ends of these hammers are each provided with an enlargement or head that strikes the bell 6 each time the hammers are dropped. The short ends of these levers are pivoted with a yieldable plug 30 that is engaged by the free ends 25 of the trip levers and are normally held out in position for engagement with said levers by an inclosed rubber 31 contained within a socket of the said short arms. When the weighted ends 24: of the trip levers and 21 are forced up the short ends thereof slip past these yieldable plugs 26 in a way to allow the tree and headed ends of the striking levers to drop against the bell thus lifting the beveled end of the plug above the end of the trip lever, whereas when the weighted ends of the trip levers are lowered the yieldable plugs are forced back suflicient to permit the short ends of the trip levers to pass and seat upon the top side of the plugs preparatory to a further operation.

From the dotted lines indicated in Fig. 1 it will be seen that as the operating end 10 of the operating lever 8 is forced down the inner end of the same lever will be thrown back against the stud 32 ina way to swing the lever 12' and its segments 16 and 17 in a manner to alternately raise and lower the trip levers which serve to operate the striking hammers. These opertions may be repeated from time to time in a manner to produce alternate strokes of the levers on the bell and a series of such strokes with each operation of the foot lever.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. In a bell of the class described, the combination of a casing, a bell carried thereby, a bell crank lever pivotally mounted to the casing having a short arm projected from the casing and a long arm hung within the casing, a segment lever pivotally hung within the casing and including a long arm and a short arm having two segments formed on its outer end, means connecting the long arms of the two levers whereby the second lever may be operated by the first lever, a pair of trip levers pivoted within the casing and each including a short arm, a weighted long arm and a lug upon each of the long arms to engage the segments, a pair of hammer levers also pivoted to the casing and each including a long arm to strike the bell and a short arm to be engaged by the trip levers.

2. In a bell of the class described, the combination of a casing, a bell carried thereby, a bell crank lever pivotally mounted in the casing having a short arm projected from the casing and a long arm hung within the casing, a segment lever pivotally hung within the casing and including a long arm and a short arm having a segment formed on its outer end, means connecting the long ends of the two levers whereby the second lever may be operated by the first lever, a trip lever pivoted within the casing and including a short arm and a weighted long arm and a lug upon the long arm to engage the segment, and a hammer lever also pivoted to the casing and including a long arm to strike the bell and a short arm to be engaged by the short arm of the trip lever.

3. In a bell of the class described, the combination of a casing, a bell carried thereby, a bell crank lever pivotedly mounted to the casing, a segment lever pivotedly hung within the casing, means for connecting the two levers whereby the second lever may be operated by the first lever, a pair of trip levers pivoted within the casing and resting upon the segment, a pair of hammer levers also pivoted to the casing and each including a long arm to strike the bell and a short arm to be engaged by the corresponding trip lever.

4:.
